SPECIFICATION forming part of Letters Patent No. 378,161, dated February21, 1888.

Application filed December 9, 1886. Serial No. 221,091. (No model.)

To all whom it 72mg concern:

Be it known that I, Gnonon D. BLossoM, of Fulton, in the county ofOswego, in the State of New York, have invented new and usefulImprovements in Stoves or ,Furnaces, of which the following, taken inconnection with the accompanying drawings, is a full, clear, and exactdescription.

This invention consists in an improved con struction of a sinuousair-heating conduit extending radially into one side of the fire-pot andformed with sloping sides, and arranged with its base near the base ofthe firepot, and with grate-surface around the base of said conduit,thereby crowding the fire from the center of the fire-pot toward thesides thereof, and at the same time, by direct contact ofsaid conduitwith the fire, heating the air circulating through the conduit, whichdischarges the heated air into the apartment of the building to beheated, thereby obtaining an air-heater which is simple andcomparatively inexpeir sive in construction, superior in itssuiiiiciency over other analogous heaters, and also contributes to theheating capacity of the stove.

In the annexed drawings, an elevation and partly a vertical sectionalView of a stove embodying my improvements. Fig. 2 is a horizontalsection on line m as, Fig. 1; and Fig. 3 is a vertical transversesection on line y 3 Fig. 1.

Similar letters of reference indicate corresponding parts.

A represents the fire-pot, a the grate, and B the subjacent ash-pit, ofa stove used for heating buildings. The form of said stove is immaterialto my in vention. The fire-pot is the essential part to which myinvention pertains.

Into the fire-pot A, I extend a sinuous airconduit, 0, the ingoingportion of which enters the lower portion of the fire-pot from one sidethereof, and the outgoing portion lies over the top of the ingoingportion and is extended out through the same side of the firepot. Thisair-conduit is arranged radially in the fire-pot, and is preferably oftriangular form in crosssection, with a horizontal partition, 2),extending part way inward, as shown in Fig. l of the drawings. By thetriangular form the sides of the conduit become sloping from the top ofthe outgoing portion to the. base of the ingoing portion of saidconduit, and

Figure 1 is partly pacity of the stove, and at the same time rethe baseof the inner end or return portion of the conduit is of semicircularform, leaving sufficient grate-room around the base of the air-conduit Cto admit the requisite air for producing combustion of the fuel. Thesloping sides of said conduit prevent the fuel from lodging thereon andat the same time crowd the heat from the center of the fire-pot outwardto the sides thereof, and thus produce greater radiation of heat fromthe exterior sides of the fire-pot. The receiving end (I of theair-conduit O is extended downward and may be either terminated at ornear the floor of the apartnientin which the stove i-slocated orextended to the exterior of the building to receive fresh air. Thedischarge end 6 of the aforesaid air-conduit is extended upward on theoutside of the stove to asuificientcleva'tion to producea draft throughtheair-conduit. The airpassing throughthesameisintenselyheated bycontact with the walls thereof, which are surrounded and in directcontact with the fire in the fire-pot; hence it will be observed that bythe combination of the air-conduit O with the fire-pot A, in the mannerdescribed and shown, I greatly increase the heating eaduce thegrate-surface in such a manner as to economize in the consumption offuel.

Having described my invention, whatI claim as new, and desire to secureby Letters Patent, is-

In combination with the fire-pot, the airheating conduit O,extendinginto one side of said fire-pot part way the width thereof, and arrangedwith a grate-surface around its base, and provided with the horizontalpartition 1), extending part way the length of'the conduit 0, and thereceiving-pipe d and dischargepipe 6, communicating with said conduit,respectively, below and above the partition I), substantially in themanner described and shown.

In testimony whereof I havehereunto signed my name and aifiXed my seal,in the presence of two attesting witnesses, at Syracuse, in the countyof Onondaga, in the State of New York, this 8th day of November, 1886.
